III. Teams and Players

A. Number of players on team: No team may have more than six members
in total, all of whom must be named before that team begins play. All players
must be current members of the BPAA.

B. Number of Players on Field: No team may have more than four
players on the Playing Field while the ball is in play. Tournaments may
be held with fewer than four players per team allowed on the field, but
in no case may the limit be less than two. Tournaments may also be held
which limit the number of male or female players on the field.

C. Team colors: Each team must have two sets of shirts, each set
to include a different numbered shirt for each member of the team. The
shirts in each set must be identical in color and pattern, and have clearly
visible numbers at least ten inches high on the back and four inches high
on the front. Color-coordinated shorts, helmets, pads, and numbers on the
sleeves are optional, but recommended. Any sponsors’ logos must be configured
in such a way as not to interfere with the legibility of the players’ numbers.
The two sets of shirts must be sufficiently different in color and pattern
as to enable the team to avoid having to wear shirts which cause confusion
with their opponents’ shirts.

D. Conflicting Colors: If, in the opinion of the officials, two
teams’ shirts are so alike as to cause confusion, the team lower in the
draw shall be required to switch to their other set of shirts. If there
is no way to determine which team is lower in the draw, a coin flip shall
decide which team shall change shirts.

E. Substitutions:

1. Between Periods: Substitutions may be made between periods,
but a team making such substitutions must remain within any limitations
regarding number of male or female players on the field.

2. Injured player:

a. If a player is unable to continue play due to injury or illness,
a substitution may be made during a period. If possible, a team should
still remain within any restrictions on the number of male or female players
on the field, but a female player may be substituted for a male player
in this situation.

b. Any player who leaves the game due to injury or illness may
not return to the game until the end of the the period following that during
which the player left the game. (e.g. if a player leaves the game during
the second period due to injury, he or she may not return to the game until
after the third period.)

c. If a player is injured by a foul, a Penalty 4 may be appropriate;
see Penalty 4.

F. Captains:

1. Each team shall designate one player as its Captain, who shall
have the sole right to discuss any matter with the Referee.

2. If a team’s Captain is not on the field, an Acting Captain
shall be designated from among the players on the field until the Captain
returns to the field.
